Window Guide · Mumbai
West-facing Dining Room
West is the ideal Vastu direction for a dining room. warm-humid climate adds specific window-design choices.
The recommendation
These figures are advisory — drawn from IS 3792 (Warm-Humid zone) and Vastu Shastra teaching tradition. An architect should adapt them to your plot's exact bearing, plinth height and facade design.
Why this direction for a dining room?
Dining-room windows want soft, even light during meal times (especially evening) and connection to the kitchen-side air for serving comfort. A west-facing window with light afternoon shade is the classic choice — it catches the soft golden hour during dinner.
Children, gains, dining. The afternoon-light direction — manage with shading.
Vastu's ideal placement for a dining room is W — West sits in this band.
Why Mumbai's climate matters
Mumbai is in the Warm-Humid climate zone (Aw, Am, Af per the Köppen scale; Warm-Humid per NBC 2016). Summer temperatures: 30-38°C, winters: 18-28°C. Rainfall: 1000-3000 mm/year. Humidity: >70%.
Verandahs are not decoration here — they are the building's lungs. Skip them and the house cannot breathe in monsoon.
For a west face in this climate, the recommendation is a sliding 2t (cross-ventilation) window with clear glazing and a sill at 3.5' — calibrated for year-round high humidity, moderate temperatures, and monsoon-driven cross-ventilation.
Common mistakes
- Mirror directly opposite the dining table reflecting food / diners
- Sliding doors instead of windows — diners feel exposed during meals
- Diners face the glare of an unshaded west window during evening meals
- Treating it as an air-conditioning problem — in Mumbai's humidity, cross-ventilation across opposite walls always beats sealed AC reliance.
